During the coup, Aegon fought Lady Baela Targaryen, both mounted on their dragons Sunfyre and Moondancer, respectively. The dragons fought in the pre-dawn sky above the castle, eventually slamming into the yard still fighting. Aegon jumped from the saddle twenty feet from the ground but Baela crashed to the ground with Moondancer. Marston stopped Alfred from slaying the burned girl as she crawled away from her dying dragon, and Tom Tangletongue carried her to the maester.[1]

Aegon II shattered his legs in a fall during the fight, but he refused milk of the poppy because of his experience with it during his recovery after Rook's Rest.[1]
